Description

one

The invention relates to the field of machine building, instrument making and metal working.

Vibrating machines for grinding, polishing and cleaning parts are known, which contain an unbalance vibrator with turning weights held by springs in their original position.

The peculiarity of the described vibrating machine is that, along with the moving weights, the weights of the vibrator are counterweights, the unbalancing moment of which is equal to the original unbalance of the moving loads and directed in the opposite direction. This allows one to rule out unbalance and to arrange the buildup of the comteyner B of the reisiais zone.

FIG. Figure 1 shows schematically the described vibration machine; on fi1. 2 shows the weight and counterweight of the vibrator in the initial position; in fig. 3 - the same weight and counterweight in working position.

The machine contains the vibrator shaft 1 and the container 2 mounted on the frame 3, which is attached to the base through elastic elements 4. The vibrator shaft is connected to the drive 5 through elastic couplings 6. The unbalance movable load 7 and the fixed weight counterweight 8 are fixed on the pivot shaft.

The base load is held by the spring. 9. The departure amount of the load of the load is regulated by nut 10 and 11.

When the motor is turned on, the vibrator shaft starts turning, increasing the speed of rotation in accordance with the characteristics of the motor and the mass of the load.

At the initial moment, due to the balanced position of the weights 7 and the counterweights 8, the frame with the container is at rest. As soon as the magnitude of the centrifugal force acting on the weights exceeds the value of the force of the deformed spring 9, the weights 7 will turn to the hinge axis and take up a given operating limit. After that, the frame begins to oscillate with the container and the parts are machined.

After the motor is turned off, the speed of rotation of the vibrator shaft decreases, and after the magnitude of the centrifugal force acting on the weights turns out to be less than the force of the spring, the weights turn and occupy the original balanced position. The container frame with the container is stopped.

Subject and d on and e and

A vibrating machine for grinding, polishing and cleaning parts, operating in a resonance zone containing a container.

mounted on a sprucely mounted rim, the drive and unbalance vibrator with movable weights held in the position of minimum unbalance by springs, is different, and because of eliminating the buildup of the container in the resonant zone by eliminating debalance, on the vibrator shaft with counter-weights mounted counterweights, the moment of unbalance of which is equal to the initial moment of unbalance of movable goods II, is in the opposite direction.
